Underlying Theme of Colligative Properties of Nonvolatile Solutes = the inability of solute particles to cross phase boundaries/membranes a) solutes can't enter the gas phase → lowers a solvent's VP → increases a solvent's BP b) solutes can't enter the solid phase → lowers a solvent's FP c) solutes can't cross semipermeable membrane → osmotic pressure development So…. . The presence of a nonvolatile solute decreases the

Unformatted text preview: mole fraction of the solvent, thereby decreasing the number of solvent particles leaving the solution per unit time. this decrease causes an adjustment in the equilibrium (i.e., Le Chatelier Principle) this adjustment to reach a new balance in numbers of particles crossing between phases/membrane per unit time results in the measured colligative property...
